Due to too large a variety of copy-protection mechanisms for the normal consumer the keep track of, some of which prevent playing of CDs and DVDs on certain devices (inadvertently or deliberately), consumers can no longer be sure of being able to play a given CD or DVD they might have considered buying. Throw in single-region DVD players, and you've got consumer frustration: to prevent the experience of not being able to use an item that we've forked out 10 to 15 Pounds for, we simply don't buy.
As a result of this, the record industry will vanish, while the live music business will remain. And with the simultaneous demise of music television, we'll be seeing less of Britney and more of Wynton. I'll toast to that.
